Yes it is a hyperbole. Billionaires aren’t literally buying bunkers and armed guards. They are however buying superyachts, private jets, acres of remote property with private airstrips, fenced mansions in heavily policed areas (including inside many dictatorships), etc. These together function as a bunker with armed guards to protect them against the effects of climate change. When it is too smokey in Claifornia where one of your mansion is, simply fly your private jet to Kamchatka where you last parked your superyacht. Or if it is also smokey in Kamchatka, you have a smaller yacht parked in Patagonia. Are you in Florida and another hurricane is on its way? Notify your private chefs in Egypt about your plans to stay in your palace over there for the next 3 weeks.
